SPECIFICATION forming part of Letters Patent No. 690,321, dated December 31, 1901.

Application filed September 12, 1901. Serial No. 75,179. (No model.)

To all whom it may concern:

Be it known that I, KENNETH RUSHTON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Trucks, of which the following is a specification.

My invention relates to certain improvements in trucks, especially those to be placed under electric locomotives and cars.

The object of my invention is to make the truck from merchant plate, so as to reduce the cost of manufacture and at the same time to make a substantial and easily-riding truck. This object I attain as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a side View of my improved truck. Fig. 2 is a plan view of one-half of the truck, and Fig. 3 is a transverse sectional view of the same.

A is the frame of the truck. This frame consists of two side bars A, made of merchant plate, and cross-bars A at each end, also preferably made of merchant, plate, bent and bolted to the side bars, as shown. I preferably use for the side bars steel plates rolled to the proper thickness and of an even width, although in some instances they may be made of sheet-steel cut to shape.

B is a metallic cross-frame extending from one side plate A to the other across the center of the truck. This frame B has flanges b at each end, which are secured to the side plates A by bolts 0. The quadrangular frame made up of merchant plates is substantial, rigid, and economical.

E is the spring-plank, hung from the crossframe B by links 6 e, and supported on this spring-plank are coiled springs F, carrying the-bolster G, which is guided in the frame B in the usual manner. On this bolster is the usual center plate.

The side plates A are cut out at a, and secured thereto are the pedestal-castings D D. In these pedestal-castings are mounted the usual boxes 61, in which are journaled the axles of the wheels of the truck.

It will be noticed in referring to Fig. 3 that the pedestal-castings are secured to the outside of the truck-frame. construction is to allow for the placing of the springs H H on the outside of the truck-frame and yet be directly above the boxes d, which are guided in the pedestal-castings D. These springs are the ordinary type of elliptical springs, the center strap of each spring resting upon its box d, while the ends of the springs rest within loop shaped brackets I, made in the present instance of wrought metal and secured to the side frame by bolts. (Clearly shown in Fig. 3.)

By-the construction above described I can use elliptical springs, so as to obtain ease of action and yet have sufficient room between the side plates of the truck for the brake mechanism and motors.

I claim as my invention 1. The combination in a truck, of the side plates of an even width throughout, and end plates secured thereto, a cross-frame secured to the side plates, the whole forming a rigid truck-frame, said side plates being recessed, pedestal-castings secured to the outside of the frame at the recesses, boxes in the pedestalframes, and springs mounted above the podestal-frames and bearing upon the boxes, substantially as described.

2. The combination in a car-truck, of a frame having side plates made of metal of an even width throughout, transverse end plates secured to the side plates, and acentral transverse frame secured to the side plates, pedestals secured to the outside of the said side frames, boxes in said pedestals, projecting brackets secured to the side frame at each side of each pedestal, and elliptical springs having their ends resting against the brackets and their centers resting upon the boxes, substantially as described.

3. The combination in a car-truck, of side plates quadrangular in cross -section, end plates secured to the side plates forming the quadrangular frame, a transverse frame having wide flanges at each end, said flanges secured to the side plates of the truck-frame, pedestals secured to the outside of the said side plates, the frame being notched between the pedestals, journal-boxes mounted in the The object of this pedestals outside the side frame, springs name to this specification in the presence of mounted on the outside of the frame and resttwo. subscribing Witnesses. ing on the boxes, a spring-plank, links con- 1 necting said spring-plank with the cross- KENNETH RUSHPON 5 frame, and a bolster carried by the plank, \Vitnesses:

substantially as described. JAs. H. M. HAYES,

In testimony whereof I have signed my WILLIAM DE KRAFFT.
